OpenVSwitch Installation problem

When I try to install and configure openvswitch on 8.3 getting the following error

ovs$ rpmbuild -bb --nocheck ~/rpmbuild/SOURCES/openvswitch-2.9.2/rhel/openvswitch_no_kmod.spec
error: Failed build dependencies:

dnf install centos-release-openstack-train

Anyone aware about this

ModuleNotFoundError: No module named ‘six’
Could not import extension sphinx.builders.applehelp (exception: No module named ‘pygments’)

AlmaLinux can’t support OpenVSwitch now. lack of related cloud yum repo.
please wating.

I have compiled it with source and working fine now thank you.

So you mention you have compiled it and its working… I’ve compiled it per the basic instructions and installed it, but startup scripts, locations, etc are all missing in the basic installation of 2.15.0. Looking closer, there is the ability to make the RHEL rpm from the package that has all the missing scripting to make the package usable. I can do those installs by hand however I’d rather have a package that I could install using RPM… More work on how to make that happen.

I would like to understand what you did when you say “it works fine now”.
